AXEL JOHNSON, OF OAKLAND, CALIFORNIA, ASSIGNOR TO AMERICAN CAN COMPANY, OF SAN FRANCISCO, CALIFORNIA, A CORPORATION OF NEW JERSEY.

Specification of Letters Patent.

Patented Apr. it, 1919.

Application filed January 4, 1916. Serial No. 70,226.

To all whom it may concern:

Be it known that I, AxnL JOHNSON, a

citizen of the United States, residing at Oak land, in the county of Alameda and State of California, have,invented certain new and useful Improvements in Apparatus for "Applying Ring-Liners to Can Ends, of which the following is a specification.

The present invention relates to'can making machinery, and more particularly to an apparatus, for applying ring liners to can en 5. Machines for this purpose, asat present constructed, are of theintermittent type, in which a can end is advanced by a series of step movements, and aring liner applied thereto during a period of rest. This in-' volves the intermittent operation, and the starting and stopping of a large number of parts in the machine, some of which have considerable weight, and a consequent loss of power ensues, as well as unavoidable wear and tear.

The object of the present invention, there fore, is to provide a machine for the described purpose in which the can ends are continuously moved along by a conveyer, and ring liners successively deposited thereon, while said ends are moving. The result of this continuous operation is greatly increased speed, capacity, and smoothness of operation, with the expenditure of less power.

In order to comprehend the invention, reference should be had to the accompanying sheets of drawings, in which Figure 1 is a plan view of the machine, a portion of the casing being broken away to show the interior Working parts.

Fig. 2 is a vertical longitudinal section through the center of the machine, taken in the direction of the arrows on the line w w of Fig. 1 of the drawings.

7 Fig. 3 is a vertical transverse section, taken in the direction of the arrows on the line g of Fig. 1 of the drawings.

- Fig. 4 is a fragmental vertical section taken in the direction of the arrows in the line zz of Fig. 3 of the drawings, showing the driving mechanism.

Fig. 5 is a detailed perspective view, enlarged, of the ring liner holder and a por tion of the turret, certain parts being broken away for the sake of clearness.

Fig. 6 is a detailed perspective view of a positioned can end, a ring liner, and a plunger for applying the same, the parts being separated to show their relative POST? tions.

In the drawings, and referring more particularly to. Figs. 1 and 2 thereof, the numeral 1 represents a suitably constructed supporting frame or bed having a laterally extending bracket 2, and supporting a horizontal table 3. A semi-cylindrical casing or drum 4, supported by a vertical circular end-plate 4', Fig. 3 of the drawings, rests upon the table 3,-and has within it an axially disposed-shaft 5, extending from and fixed to a central hub 4 in said end plate 4. Journaled for rotation upon said shaft 5 is a turret 6, having a cylindrical rim 6, of such size as to closely fit but yet freely rotate within the drum 4. A thrust collar'7 retains said turret upon the shaft 5.

A transverse drive shaft 8, Figs. 1, 2, 3 and 4 of the drawings, is suitably journaled in the frame 1, and is provided with means, as, for example, a belt pulley 9, for receiving power from an outside source, not shown in the drawings. Said drive shaft 8 carries a gear '10, which drives the turret 6 by means of a train of intermeshing gears 11 and 12, Figs. 2 and 4 of the drawings, and a series of gear teeth 14 cut in the periphery of said turret 6, Figsrl, 3, 4 and 5 of the drawin The turret rim 6' is provided interior y with a series of inwardly projecting bosses 15, Figs. 2, 3 and 5 of the drawings, opposite each of which there is an opening 16 in the web of the turret 6. A seat or recess for receiving and conveying the ring liner, preferably a circular groove 17, the exact diameter of the ring liners to be applied, is cut into the exterior face of the rim 6' over each boss 15, and extended down 'thereinto, and centrally of each of said circular grooves 17 a hole 18 is formed through each boss 15. A ring 19 lies within each circular groove 17, said ring being formed with a diametrioal cross bar 19'. Figs. 1, 2, 5 and 6 of the drawings, to which is attached an axially disposed stem 20, adapted to slide within the radial hole 18.' A pin 20', passing through the inner end of said stem 20, limits the outward movement thereof. The turret rim 6 is formed with a circumferential groove 21, in which the cross bars 19 of the rings 19 rest, as shown in Figs. 1, =2, 3 and 5 of the drawings. The inward movement of the ring 19is limited by a series of adjustable stops 22 carried by the web of the turret 6, against which the inner ends of the stems 19 abut.

Supported by the upper part of the drum 4, in the path of travel of the grooves 17 in the turret rim 6, is a suitably constructed holder 23 adapted to contain a stack of ring liners 24. The lowermostliner of said stack normally rests upon the traveling surface of the turret rim 6, and is held in contact therewith by a weighted follower 25, Figs. 1 and 5 ofthe drawings, the lower surface of which is formed with the same curvature as that of said rim 6. The clearance between the exterior of the turret rim 6 and the interior of the drum 4: is less than the thickness of one ring liner, so that the lowermost of the series of liners 24 can not escape from said holder 23 until one of the circular grooves 17 passes therebeneath.

The plunger rings 19, which during that part of their travel lying above the axis of the turret are held by their own weight within their respective circular grooves 17, are so adjusted as to position by means of the stops 22, that their upper surfaces are below the surface of the rim 6 by a distance equal to the thickness of one ring liner; that is, so that each groove 17 will contain but one ring liner. Therefore, when a groove 17 passes beneath the holder 23, the lowermost liner 24: therein drops into said groove, and is retained therein by the closely fitting drum 4, until the groove 17 reaches the lowest point of its travel. At this point, indicated at A in Fi 2, of the drawings, the plunger ring 19 is allowed to drop, by its own weight, thus forcing the ring liner 24: into the flange 27 of a positioned can end 26, said end be ing advanced along the table 3 by a conveyer chain 28 provided with spaced upstanding lugs 29 for engaging the can ends 26. The chain 28 is suitably supported and driven, as by means of an idler sprocket 30 and a driving sprocket 32 mounted upon the drive shaft 8. Guide rails 33 are provided on the table 3, on either side of the conveyer chain 28, to retain the moving can ends 26 in the desired path.

The movement of the conveyer chain 28 and the rotation of the turret 6 are so timed that each can end 26 is correctly positioned at the point A, Fig. 2 of the drawings, to receive a ring liner Ql'fIOlll a groove 17 in said turret 6. The can ends, after re ceiving the liners in the described manner, are carried on by the conveyer chain 8, and removed from the machine in any suitable manner, not shown in the drawings. The plunger rings 19 remain in their outer positions, as shown in Fig. 2 of the drawings, until' they are again inverted by their circular travel, and fall back into their respective grooves 17 by the force of their own weight.

I am aware that changes may be made in the form and construction of the working parts of my device, without in any way affecting the principles involved, and I therefore do not wish to limit in self in this regard, but on the contrary wish to claim the invention as broadly as I may.
